To all whom it may concern: 7

Be it known that l, FRED HOLLAND, a subject of the German Emperor,residing in Long Island City, Queens county, State of New York, haveinvented certain new and useful Improvements in Fly-Screens, of whichthe following is a specification.

My invention relates to screens of wire netting and the like of thegeneral type commonly used in windows of dwellings, ofice buildings andother edifices, for the purpose of excluding flies, mosquitos andinsects generally.

My invention relates particularly to screens of the class specifiedwhich are adapted to be permanently mounted in position but are soarranged that in the winter time, whenthe screens are not needed, and.when it is necessary to get at both sides of the window for cleaning orother purposes, the screen can be quickly and easily removed frominfront of the window.

The object of my invention is to provide a screen of the class referredto which can be permanently mounted on the outside of a window in such away that the screen proper can be rolled up at the end of the windowwhen it is desired to have access to both sides of the window forcleaning and other purposes, or during the cold season when screens areno longer required. When thus rolled up the screen is protected fromrain, snow. moist air, gases and the like.-

A further object of my invention is to provide a screen as justdescribed which can be permanently attached to buildings withoutdetracting from their appearance and without in any way interfering withthe usual operation of the window sashes.

My invention will be betterunderstood by referring to the accompanyingdrawing in which Figure 1 represents an outside View of a Windowprotected by a preferred form of my improved screen; Fig. 2 represents asection taken along the line 22 of Fig. 1; Fig. 3 represents an insideor rear View of the window shown in Fig. 1; Fig. 4 is a view, similar toFi 1, the lower half of the window being roken away, however, and theroller being shown in a central section; Fig. 5 is a section taken alongthe line 55 of Fig. 4; Fig. 6 is a section taken the shaft.

along the line 66 of Fig. 4; and Fig. 7 is an end view of the upper partof Fig. 4 taken from the right.

In the drawings, the window casing 1 is represented as of the usual typeprovided with two sliding sashes 2 and 3. My improved screen is shown aspermanently fastened upon the outside of this window casing andcomprises a tubular housing 4 having ends 5, these-ends being attachedto brackets 6, which are themselves perma nently attached to theexterior window frame 7 just above its opening. Facing each other onopposite sides of frame 7 is a pair of metal guide strips 8 havinggrooves 9 on the innerside thereof. These strips extend from the underside of housing 4 to the sill member 9 of the window frame and arepreferably attached to the side members of the frame by screws. Thesestrips also extend inwardly into the opening of the window frame and areprovided on their inner side with pairs of oppositely located lockinglugs 10 having the shape of wedges with their thick ends down.

The housing 4 is provided with a shaft 11, the ends of which are squaredoff and fixedly held in corresponding openings provided in the brackets6. This shaft carries a tubular roller 12 comprising a pair ofsubstantially semi-circular segments 13 whose ends are attached to hubs14 loosely mounted upon To each of these hubs is fixed one end of asuitable helical spring 15, the inner ends of both springs beingattached to hubs 16 which are themselves pinned or otherwise fixed tothe shaft on each side of the center thereof. Between the two hubs 16 isa spacing disk 17 to which the roller 12 is fastened. This disk 17 fitsloosely upon the shaft and prevents any longitudinal shifting of theroller.

The netting 18 should be of metal of any preferred mesh and is attachedalong its upper edge to the roller 12. Its width is substantially thatof the opening of the window frame 7 so that the edges thereof extendwell into the grooves 9 of the lateral strips 8. The lower edge of thenetting is clamped fast between the verical members of a pair of angleirons 19.

Pivotally attached spring locking members 20 are disposed at each end ofthe inner angle iron 19 and have their outward ends normally pressingagainst the strips 8.

The operation of my improved screen is as follows: With the screenraised to its uppermost position, substantially the entire netting isrolled upon the roller 12. When in this position the springs 15 shouldhave, preferably, but a small amount of tension. The lower horizontalmembers of angle irons 19 will rest against the lower side of the topmember of the window frame and against the lower side of the housing 4respectively, thus very completely closing the slot in the housingthrough which the netting is raised and lowered. To insure that thehousing shall be still more tightly closed, when the netting is in thisextreme upward position, a weather strip 21 may be attached to andacross the lower part of the housing with its inner edge substantiallyin contact with the netting. This will prevent snow, rain, moist air.and corroding gases from getting into the housing and injuring thenetting.

The screen may be lowered from either side of the window by grasping theangle iron 19 and drawing the netting down. As the locking members 20reach the locking lugs 10 they will ride up upon the inclined surfacesthereof and drop back beneath the base of the lugs so as to prevent thenettmg from rising unless the locks are suitably pressed by hand. Whenthe netting is in its extreme lower position, the angle irons 19 will beagainst the base member of the window frame. In order to provide thatthere shall be no opening whatever between the bottom Of the angle iron19 and the base member ofthe window frame, I preferably attach a stripof felt 22 or some equivalentmaterial to the under side of the angleiron. The locking lugs 10 being suitably located, this felt strip willbe placed under a certain amount of pressure when the netting iscompletely lowered and the space will thus be filled.

As will have been seen, my improved screen is a permanent unitarystructure which can be permanently attached to the window to beprotected and left indefinitely. With the screen lowered, thewindow isperfectly protected from flies and insects. In this position the screencannot be opened from the outside except by destroying the netting. Whenit is desired to wash the windows, the screen. can be raised partiallyor completely by merely releasing the spring locks 20 and allowing thespring to draw the netting upward. In the winter time and at all timeswhen it is not necessary to screen the window, the screen may be raisedto its uppermost position.- When in this position the netting iscompletely inclosed by the housing 4 and protected thereby from snow,ram, moisture and corrosive gases.

I have shown my screen with the locking members 20 on the inner sidethereof but if for an reason it should be preferred to control t escreen from the outside rather than from the inside, these lockingmembers could be placed on the outside of the screen Similarly, while itwill generally be preferred to place the screen as a whole on theoutside of the window frame, it may, nevertheless, if desired, beequally well mounted on the inside. Also, if preferred, the housing 4:may be placed vertically against a lateral member of the window casingand the netting be moved sidewise instead of up and down.

The locking lugs 10 and sprin locks 20 enable the net to be stoppedon yat certain predetermined positions. Any other usual arrangementmay,however, be substituted for these locking lugs and spring.

locks, and if desired some arrangement may be employed for enabling thenetting to be stopped anywhere within its limit of movement.

The tubular housing and guide strips are preferably-fastened together aswell as individually attached to the window casing. In this way theentire structure may be quickly attached or removed.

Having described my invention, I claim In an article of the classdescribed, in combination with a window casing, a tubular housing fixedto the outer side and above the opening thereof said housing having anarrow slot at the bottom and inner side, a shaft within said housingwith its ends fixed to the ends of the housin a roller rotatably mountedupon said she t, a spring connecting said shaft and said roller, a stripof netting passing through the slot and having an edge fastened to theroller,

ide strips at each side of the window casing with which the lateraledges of the netting are adapted to engage, means for preventinglongitudinal movement of the roller and means for locking the netting inpredetermined positions with reference to the window casing.

In testimony whereof I have hereunto set my hand.

FRED ROLLAND.
